9 / 16 page SM1350AAQM SEIKO NPC CORPORATION - 9 Melody Output Circuit The volume control circuit comprises a P-channel current-summing D/A converter, a built-in constant-current source and an external variable resistor. Output circuit (A-class) The A-class output circuit comprises a single 10-bit D/A converter with current output on SP. The D/A converter is set ON immediately after the oscillator starts, and the current output that results is the center point above and below which the converter current output varies in response to the waveform amplitude. The SP output is current-to-voltage converted for connection to audio equipment or amplifiers. The 4 sound generator waveforms are time multiplexed, so an integrating circuit must be connected between SP and the amplifier to recover the signal.

One-shot melody output (LH=LOW) One-shot melody is a melody control that stops melody after it play to the last of the melody when there is a start trigger. When STN goes LOW during melody output, the melody specified with S0 to S3 is played #N #N #M #M STN S0 to S3 Melody Output (SP pin) Figure 5. One-shot mode One-shot mode repeat function In one-shot melody mode, the output repeats the same melody while STN is LOW. When STN goes HIGH, the output continues until the end of the currently playing melody and then stops. #N #N #N STN Melody Output (SP pin) Figure 6. One-shot melody repeat timing |
